  • the formwork element according to the invention is structurally designed as a composite construction.
  • the individual functional layers are bonded together by adhesives.
  • the adhesive strength of the adhesive bonds is caused by adhesion and cohesion. Cohesive forces bring about both the internal cohesion of the adhesive and of the joining part or composite partner or substrate.
  • the cohesion between adhesive and adherend is caused by adhesion forces.
  • Adhesion is divided into mechanical and specific adhesion.
  • Adhesion promoters are used in addition to surface treatments which, in the form of mechanical and / or chemical processes, serve to either facilitate or enhance the formation of physical and chemical intermolecular forces. Adhesion promoters are often referred to as "chemical bridges" and either applied to the adherend surfaces or added to the adhesive. They lead to an improvement in the strength of the bonds.
